Look i know i just ask this question but no one will and i don' understand how to do this so .

1.solve the system of equations.
x + 3y = 5
-x + 6y = 4

a) x = 1, y = 2
b) x = 2, y = 1
c) x = 1, y = 1
d) x = 0, y = 2

2.which statement about the pair of equations is true?
2x + 3y = 14

4x + 6y = 28

a) the pair has no solutions because the equations are dependent.
b) the pair has no solutions because the equations are not consistent.
c) the pair has an infinite number of solutions because the equations are dependent.
d) the pair has an infinite number of solutions because the equations are independent.

3.which relation does not represent a function?
a) a vertical line
b) y = 5/9x-3
c) a horizontal line
d) {(1, 7), (3,7), (5, 7), (7,7)}
